I have enabled the "Display accent color on the title bar and window borders" option in Windows settings. I applied the Mica effect to my Python program using the Win32API. The window display effect, the window Style viewed with Spy++, and the code are as follows: However, I would like to emphasize that the accent color should be displayed on the window border, not the window title bar, as shown in applications like the Microsoft Store, Windows Settings, and Outlook (new). How should I modify my code?

However, I would like to emphasize that the accent color should be displayed on the window border, not the window title bar, as shown in applications like the Microsoft Store, Windows Settings, and Outlook (new).

How should I modify my code?

First of all, I suggest that you set 'Show accent colors on titile bars and window borders' to 'off'. You can modify the border to use the system accent color via DwmSetWindowAttribute with DWMWA_BORDER_COLOR. To obtain the user’s accent color, you can ask the UISettings object for the current color value of UIColorType.Accent.

For more details about how to obtain the user’s selected accent color, you could refer to the Blog: https://devblogs.microsoft.com/oldnewthing/20170405-00/?p=95905

And I suggest you could refer to the link: https://github.com/MicaForEveryone/MicaForEveryone/issues/275

Isn't this function used to obtain all access permissions and/or a complete list of owners and groups for a specified object?
